SPVM::Document::EnvironmentVariables - Environment Variables

Description

This document explains environment variables.

Environment Variables

If an environment variable is an empty string, it is treated as an undefined value.

SPVM_BUILD_DIR

A directory for files generated by the compiler and linker.

C source codes for precompilation, dynamic link libraries and object files are stored into this directory.

These files are output when attempting to build a module containing methods with the native attribute or the precompile attribute.

If these files are output and the directory given by the SPVM_BUILD_DIR environment variable does not exist, an exception is thrown. Examples:

# bash
export SPVM_BUILD_DIR=~/.spvm_build

# csh
setenv SPVM_BUILD_DIR ~/.spvm_build

SPVM_CC_DEBUG

If the SPVM_CC_DEBUG environement variable is a true value of Perl, debug messages and messages from the SPVM native class compiler and linker are printed to stderr.

SPVM_CC_QUIET

If the SPVM_CC_QUIET environement variable is a true value of Perl, messages the SPVM native class compiler and linker are not printed to stderr.

If it is defined and a false value of Perl, the messages are printed.

This setting has a higher priority than the quiet field of the SPVM::Builder::Config module.

SPVM_CC_FORCE

If the SPVM_CC_FORCE environement variable is a true value of Perl, the compilation and link by the SPVM native class compiler and linker are forced.

This setting has a higher priority than the force field of the SPVM::Builder::Config module.
